You have a clean booked and you take a blood thinner. You may wonder whether the team needs to know, whether your gums might bleed, and who to call if they do.
Short answer
Yes, tell the team. healthdirect Australia says you should let your dentist know which medicine you are taking. At Dentalini, hygiene care starts with your medical history and any changes since your last visit. Ask your prescribing doctor before changing anything. (Published guidance; Clinic preparation)
Why your medicine list matters before a clean
People take blood thinners for different reasons, and your dentist cannot see those reasons by looking at your teeth. You and your prescribing doctor hold the full picture. That is why healthdirect asks you to speak up. Its Blood thinners page, in the Medical procedures and operations section, says:
"You should also let your dentist know which medicine you are taking."

Our practical suggestion is to mention it when you book, not when you are in the chair. That gives the team time to think about your visit before you arrive and leaves room for questions. Healthdirect also advises telling your healthcare team when you book.
The same page says not to stop taking the medicine or change the way you take it without talking to your doctor first. It explains that the doctor's decision depends on the type of blood thinner, your medical history and the procedure. If the appointment worries you, ask your prescribing doctor about your own medicines.
A routine clean and gum care are not the same plan
Does being on a blood thinner rule out a clean? We cannot answer that for everyone. It depends on your history, your medicine, your mouth and what the clinician finds on the day. Some visits go ahead as booked, and some plans change.
A hygiene visit is also not one fixed task. Our dental hygiene page says a visit can include a gum assessment, a bite evaluation, a review of the jaw joints (the TMJ), checks of existing restorations such as fillings, and screening for oral health concerns. Some people need a routine appointment. Others, once examined, may need a more extensive plan for their gums. The clinician defines which, after looking.
So when you book, ask what the appointment is planned to cover and whether that could change after the examination. If the plan changes, you can then ask whether your prescribing doctor should hear about it before further care.
What your dentist and prescribing doctor may need to discuss
Two clinicians look after different parts of your health. Your prescribing doctor knows why you take the medicine. Your dentist knows what the planned dental care involves. Depending on your history and the care planned, your dentist may want to speak with your doctor. That is a clinical judgement made for you.
You can help by knowing:
- who prescribes your blood thinner and how to reach them
- what the medicine is called and the dose you were given
- why you take it, in your own words
If you feel unsure about any part of your treatment, ask your prescribing doctor. Decisions about your medicine belong in that conversation.
What a hygiene visit starts with at Dentalini
Our hygiene page describes how we begin, and it is the reason your medicine list matters.
- Medical history. We start by understanding your medical history, your oral health concerns and any changes since your last visit. This is the natural moment to share your medicine list and anything new.
- Examination. The visit can include gum assessment, bite evaluation, TMJ review, restoration checks and screening for oral health concerns.
- Advice that fits you. We tailor home-care advice to your needs rather than giving everyone the same script.
- Recall timing. Once your teeth and gums are stable, we recommend a three, six or twelve month recall based on your needs. healthdirect's dental check-up page, reviewed in February 2025, also bases recall timing on the health of the individual mouth.
That page also advises telling your dental practitioner or their staff if you are nervous. If your medicine, or the idea of bleeding, makes you anxious, say so at the start of the visit.
Decision aid: what to say and what to ask
Use this table as a prompt. The left column is what we find useful to hear before the clean. The right column is a question for your treating team, meaning your prescribing doctor and your dental team. It leaves out doses and blood-test numbers on purpose, because those are questions for your prescriber.
| Detail to mention before the clean | Question for the treating team |
|---|---|
| The medicine name and dose, exactly as prescribed. | Does my prescriber want to know about the dental care that is planned? |
| Why I take it, and who prescribes it. | Who should the dental team contact if they need to speak to my doctor? |
| My other medicines, supplements and allergies. | Is there anything on my list I should check with my doctor before the visit? |
| Any recent changes, and any bleeding I have already noticed. | Should my prescribing doctor hear about this bleeding too? |
| The care I have booked. | Could the plan change after the examination, and will you tell me before it does? |
| That I would like instructions in case bleeding continues. | Who do I call, and what should I do while I wait? |
Questions about bleeding, and a plan to follow afterwards
Ask these before the visit, so you have the answers afterwards:
- What would you regard as usual for me, and what would concern you?
- Whom do I call if bleeding continues, and on what number?
- What should I do at home in the first hours?
- Should I tell my prescribing doctor about any bleeding?
- Could you write the instructions down for me?
The answers are specific to you, so they are worth having in hand before you sit in the chair.
When bleeding needs prompt or urgent advice
healthdirect says bleeding that does not stop, or that lasts a long time, needs urgent medical assessment. Treat that as the line. If it is happening to you, seek urgent medical help. Do not wait for your next appointment or for a reply to a message.
For situations that are less clear, such as bleeding that worries you but is easing, call the dental team or your prescribing doctor's rooms and describe what you see. The point is to know, before your visit, who you would call and what you would do.
Checklist for your appointment
Tick these off before you ring or arrive:
- The exact medicine name and dose as prescribed
- The reason for treatment and the name of the prescribing doctor
- Other medicines, supplements and allergies
- Recent changes, and any bleeding you have already noticed
- What care is booked, and whether the scope may change after the examination
- Who to call, and what instructions to follow, if bleeding continues
If it helps, here is a sentence you can say when you phone: "I take a blood thinner. I would like to give you the name, dose and prescriber, and ask whether the care booked might change after the examination."
A different medicine question: dry mouth
Some medicines affect the mouth in other ways. That is a separate question from this one, and we cover it in Dry mouth after starting medicines: what to ask your dentist.

Frequently asked questions
Do I need to tell my dentist I'm on blood thinners?
Yes. healthdirect says you should let your dentist know which medicine you are taking. We suggest telling us when you book, with the medicine name, the dose and who prescribes it. Our hygiene care also starts with your medical history and any changes since your last visit.
Should I stop my blood thinner before a dental clean?
healthdirect says not to stop taking it or change the way you take it without talking to your doctor first. It explains that the doctor's decision depends on the type of blood thinner, your medical history and the procedure. Ask your prescribing doctor about your own medicines.
Is bleeding after a clean an emergency?
healthdirect says bleeding that does not stop, or that lasts a long time, needs urgent medical assessment. For anything less clear, call the dental team or your prescribing doctor's rooms and describe what you see. Ask before your visit who to call and what instructions to follow.
Will you still go ahead with my clean if I take a blood thinner?
The clinician decides after reviewing your history and examining your mouth. Some visits go ahead as booked, and some plans change. If the plan changes, we will talk it through with you and explain why.
Does the type of blood thinner matter?
healthdirect says your doctor's decisions depend on the type of blood thinner, your medical history and the procedure. That is why we ask for the medicine name, the dose and the prescriber. Your prescribing doctor can tell you what applies to your own medicine.
